Simplifying d2 + 11d + 16 = 0 Reorder the terms: 16 + 11d + d2 = 0 Solving 16 + 11d + d2 = 0 Solving for variable 'd'. Begin completing the square. Move the constant term to the right: Add '-16' to each side of the equation. 16 + 11d + -16 + d2 = 0 + -16 Reorder the terms: 16 + -16 + 11d + d2 = 0 + -16 Combine like terms: 16 + -16 = 0 0 + 11d + d2 = 0 + -16 11d + d2 = 0 + -16 Combine like terms: 0 + -16 = -16 11d + d2 = -16 The d term is 11d. Take half its coefficient (5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. 11d + 30.25 + d2 = -16 + 30.25 Reorder the terms: 30.25 + 11d + d2 = -16 + 30.25 Combine like terms: -16 + 30.25 = 14.25 30.25 + 11d + d2 = 14.25 Factor a perfect square on the left side: (d + 5.5)(d + 5.5) = 14.25 Calculate the square root of the right side: 3.774917218 Break this problem into two subproblems by setting (d + 5.5) equal to 3.774917218 and -3.774917218.Subproblem 1
d + 5.5 = 3.774917218 Simplifying d + 5.5 = 3.774917218 Reorder the terms: 5.5 + d = 3.774917218 Solving 5.5 + d = 3.774917218 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '-5.5' to each side of the equation. 5.5 + -5.5 + d = 3.774917218 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + d = 3.774917218 + -5.5 d = 3.774917218 + -5.5 Combine like terms: 3.774917218 + -5.5 = -1.725082782 d = -1.725082782 Simplifying d = -1.725082782Subproblem 2
d + 5.5 = -3.774917218 Simplifying d + 5.5 = -3.774917218 Reorder the terms: 5.5 + d = -3.774917218 Solving 5.5 + d = -3.774917218 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '-5.5' to each side of the equation. 5.5 + -5.5 + d = -3.774917218 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + d = -3.774917218 + -5.5 d = -3.774917218 + -5.5 Combine like terms: -3.774917218 + -5.5 = -9.274917218 d = -9.274917218 Simplifying d = -9.274917218Solution
The solution to the problem is based on the solutions from the subproblems. d = {-1.725082782, -9.274917218}
